Connecting API with TripAdvisor. Account ID

The Account ID asked for on the form under credentials do I need to input each ID for each property separately? Or will TA send me 1 Account ID for all properties as a group? Not clear on what ID# I should use.

Here's our Support Doc for TripAdvisor API connections that should walk you through the process:

However, I have a sad warning: Even though TA agreed to work with us for owners with 5 properties, they have recently been demanding a minimum of 15. We are pushing back on this, but don't be surprised if they won't hook you up since you don't have that many.
